Publication number: 20100139775Abstract: A pressure type flow control device enabling a reduction in size and an installation cost by accurately controlling the flow of a fluid in a wide flow range. Specifically, the flow of the fluid flowing in an orifice (8) is calculated as Qc=KP1 (K is a proportionality factor) or Qc=KP2m(P1?P2)n (K is a proportionality factor and m and n are constants) by using a pressure P1 on the upstream side of the orifice and a pressure P2 on the downstream side of the orifice. A fluid passage between the downstream side of the control valve of the flow control device and a fluid feed pipe is formed of at least two or more fluid passages positioned parallel with each other. Orifices with different fluid flow characteristics are interposed in the fluid passages positioned parallel with each other. For the control of the fluid in a small flow area, the fluid in the small flow area is allowed to flow to one orifice.Type: ApplicationFiled: June 22, 2006Publication date: June 10, 2010Applicants: FUJIKIN INCORPORATED, NATIONAL UNIVERSITY CORPORATION TOHOKU UNIVERSITY, TOKYO ELECTRON LTD.Inventors: Tadahiro Ohmi, Masahito Saito, Shoichi Hino, Tsuyoshi Shimazu, Kazuyuki Miura, Kouji Nishino, Masaaki Nagase, Katsuyuki Sugita, Kaoru Hirata, Ryousuke Dohi, Takashi Hirose, Tsutomu Shinohara, Nobukazu Ikeda, Tomokazu Imai, Toshihide Yoshida, Hisashi Tanaka

Patent number: 6785745Abstract: A recording/playback apparatus includes an upper control unit which transmits a composite command, which includes a real processing command and a virtual command, to a disk device. The disk device performs a process until a point of time when an operation cannot be continued unless the virtual command is changed to the real processing command to be operated beforehand. Instead of standing by after the real processing command is completed, the disk device can voluntarily operate beforehand in response to the virtual command, while selecting an optimum seek speed or disk rotation speed. The recording/playback apparatus can thus maintain the continuity of continuous data and perform an optimum operation in accordance with an expected performance while switching speeds of seek and disk rotation in detail.Type: GrantFiled: June 17, 2002Date of Patent: August 31, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Atsushi Isshiki, Kazuyuki Miura
